This is a late 2009 Mac. It has a 1 TB solid state hard drive installed by Apple technicians. High Sierra was on this computer previously. Everything has been swiped. Having some problems downloading High Sierra again. Only way I know to do it is to take it to Hardin Computer and have them do it for $50. Or maybe you can figure it out. Selling it as is for $30.
Wireless Logitech mouse full size is available for 10$.
